What do you mean by terminal?  Phone?  PC?  Green screen?

I would suggest you look at things like Skype, OpenPGP, Hushmail.  Not 
because they do what you want but because they do parts of what you want.

Anything using a browser would only be rated "medium" security in my book.

Do you really want that?  Or is it just 'cool' ?  If you really want 
that, it will take a long time.  If it is just cool, look for something 
else that might take less time :)  you can always come back...

There are lots and lots of attempts, so to some it must be worthwhile.

SSL is for client to server communications, and it is point to point. 
So for a start, everyone on the servers can read the messages.  Also, it 
is pretty much encumbered by its certificate design, so it is typically 
hard to set up and get working for the user/client.

Typically nobody cares about helping others, they are too busy on their 
own code.  The only way you can get some interest is if your system is 
famous and used by a lot of people.
